Hi MESO

If you take 10iu HGH and use metformin, Will you still get a dump in IGF. Or is this only when your body make it youself?
 
I dont. I asked in the first place, because I like to hear different View. Lots of clever people here, so you Can learn new things.
The answer is nobody actually knows if metformin affects AAS users in regards to hypertrophy,it may lower or increase IGF but so what? There are guys with 250 igf that are 250lbs lean and guys around here with 600igf at 180lbs wet....
Fact is professional level bodybuilders use metformin and don't worry ... So if metformin keeps your BG in check on high dose GH and food than I would use it and see the results....
If it bloats you like shit and you can't eat than tou have your answer ....
Like all drugs the effects and side effects are very individual and you have to try it out and monitor

All the guys quoting studies are just using them to help make decisions instead of relaying on experience sometimes the answer is the same sometimes not... Depends on how close the study was to reality...
 
[...] in participants >18 years old, metformin intake significantly increased IGF-1.
However, as to why metformin appears to elicit greater effects in children vs. adults, this requires more detailed evaluation, beyond supplement duration discrepancies

See below (yes, the authors use the wrong inequality sign, but it is clear from their discussion that the '18>' row is supposed to represent the age>18 group. And the minus sign is missing from the lower bound, very sloppy).

Well, I've also asked chatGPT this question in the past and it confirmed this as well. I'll ask it to provide sources this time as I know ChatGPT isnt exactly the gold standard.

What evidence do you have to back this claim up besides Vigorous Steve? Using Vigorous Steve as a reference is like submitting a research paper referencing Wikipedia aka not worth much.
Metformin has been shown to lower IGF-1 levels through several mechanisms. By activating the AMPK pathway, Metformin reduces insulin and glucose levels, which can downregulate the IGF-1/IGF-1R signaling pathway. This reduction in IGF-1 activity is associated with Metformin's ability to inhibit the mTOR pathway, which influences cell growth, proliferation, and aging processes. These effects may contribute to Metformin's potential anti-aging and anti-cancer properties by lowering IGF-1's role in promoting cell proliferation and survival.

Metformin's impact on IGF-1 appears to be more pronounced in hyperinsulinemic individuals or those with metabolic disorders, where insulin levels are elevated. In such cases, lowering insulin reduces hepatic IGF-1 production since IGF-1 synthesis is insulin-dependent. This reduction may be beneficial for longevity and conditions involving excessive IGF-1 signaling.

While these findings are supported by clinical and preclinical research, specific impacts vary depending on individual physiology and context of use .
